Question

Because most human characteristics are complex, many genes act together to determine a trait. this is called:

Answer 1

-pleiotrophic effect
-multiphase inheritance
-polygenic inheritance
-mutation

Answer 2

The correct answer is - Polygenic inheritance.

Step-by-step explanation:

Polymeric inheritance takes place if a trait is influenced by two or more genes at a time. The genes can be normally high in numbers but show minute influences in the particular trait.

In humans, there are many complex gene interactions that control different characters of traits such as hair color, eye color, the height of individuals, and weight or skin color. There are many more traits that show polygenic inheritance.

Thus, the correct answer is - polygenic inheritance.
